ggarrange: Arrange Multiple ggplots

Description

Arrange multiple ggplots on the same page. Wrapper around plot_grid(). Can arrange multiple ggplots over multiple pages, compared to the standard plot_grid(). Can also create a common unique legend for multiple plots.

Usage

ggarrange(..., plotlist = NULL, ncol = NULL, nrow = NULL, labels = NULL,
  label.x = 0, label.y = 1, hjust = -0.5, vjust = 1.5,
  font.label = list(size = 14, color = "black", face = "bold", family = NULL),
  align = c("none", "h", "v", "hv"), widths = 1, heights = 1,
  legend = NULL, common.legend = FALSE)

Arguments

...

list of plots to be arranged into the grid. The plots can be either ggplot2 plot objects or arbitrary gtables.

plotlist

(optional) list of plots to display.

ncol

(optional) number of columns in the plot grid.

nrow

(optional) number of rows in the plot grid.

labels

(optional) list of labels to be added to the plots. You can also set labels="AUTO" to auto-generate upper-case labels or labels="auto" to auto-generate lower-case labels.

label.x

(optional) Single value or vector of x positions for plot labels, relative to each subplot. Defaults to 0 for all labels. (Each label is placed all the way to the left of each plot.)

label.y

(optional) Single value or vector of y positions for plot labels, relative to each subplot. Defaults to 1 for all labels. (Each label is placed all the way to the top of each plot.)

hjust

Adjusts the horizontal position of each label. More negative values move the label further to the right on the plot canvas. Can be a single value (applied to all labels) or a vector of values (one for each label). Default is -0.5.

vjust

Adjusts the vertical position of each label. More positive values move the label further down on the plot canvas. Can be a single value (applied to all labels) or a vector of values (one for each label). Default is 1.5.

font.label

a list of arguments for customizing labels. Allowed values are the combination of the following elements: size (e.g.: 14), face (e.g.: "plain", "bold", "italic", "bold.italic"), color (e.g.: "red") and family. For example font.label = list(size = 14, face = "bold", color ="red").

align

(optional) Specifies whether graphs in the grid should be horizontally ("h") or vertically ("v") aligned. Options are "none" (default), "hv" (align in both directions), "h", and "v".

widths

(optional) numerical vector of relative columns widths. For example, in a two-column grid, widths = c(2, 1) would make the first column twice as wide as the second column.

heights

same as widths but for column heights.

legend

character specifying legend position. Allowed values are one of c("top", "bottom", "left", "right", "none"). To remove the legend use legend = "none".

common.legend

logical value. Default is FALSE. If TRUE, a common unique legend will be created for arranged plots.

Value

return an object of class ggarrange, which is a ggplot or a list of ggplot.
